OKLAHOMA CITY — Kevin Durant scored 40 points while Russell Westbrook added eight of his 16 points in overtime to help the Oklahoma City Thunder beat Dallas 111-105 on Thursday night for their 11th straight win at home.

Serge Ibaka added 19 points and matched his season-high with 17 rebounds as Oklahoma City charged back from 10 points down in the final 7:17 of regulation and found a way to win after losing back-to-back games for the first time this season.

Darren Collison scored a season-best 32 points for Dallas. Dirk Nowitzki scored nine points in his second game back after off-season knee surgery, showing some rust down the stretch.

Westbrook turned the game around with six straight points after the Mavs had gone up 104-101 on Chris Kaman’s bucket inside midway through overtime.
